Felines seem to be having their day in sun this week thanks in part to an exhibition in Portland, Oregon called Cat Revolution. From Compressed Pattern — the folks who made Kattbank, an ingenious bench that hides the kitty litter — and DWR’s Portland Studio, it shows the results from a competition for furniture that appeals to both felines and people. On June 21 (tomorrow) there is a silent auction, with funds being donated to the Oregon Human Society. Here are a few of the cat-happy pieces up for grabs: Above left, Wobble, a cat scratching post made by James Owen. Center, the Cat Tree Fort, by Monte Cook of FlatHED. And, right, Floor Barrel for cats to sleep inside and scratch on the outside, from Itchy Knee. For more a kitschy look at feline design, check out Animal Planet’s new “reality TV show,” Meow Mix House, where a group of adoptable cats compete for TV viewers’ affections. Their specially designed penthouse comes complete with cat-sized sofas, tables and accessories.
